I can confirm the creative labs x-fi mutes non-audio input.
i am not looking simply for a device that captures spdif. it must support spdif capture when PCM_N and/or VALIDITY channel status bits are set.
so far, all tested devices mute input when either of these bits are set, therefore blocking non-pcm bitstream capture.
ESI U24 XL: NO
minidsp: NO
Creative Labs X-Fi: NO
